HELOS is the modular classic among laser diffraction sensors. Within each HELOS the primary physical diffraction set-up is realised deploying a parallel laser beam. This yields the purest optical alignment for analysis of extended special arrangements of particle collectives which allows for size characterization beyond limiting assumptions and constraints.

The proven HELOS series – with its classical parallel beam laser diffraction set-up – offers a powerful technology for particle size distribution analysis of powders, granules, suspensions, emulsions, sprays and numerous other particulate systems. A size range from below 0.1 µm to 8,750 µm is mastered. The modular sensor reveals its true superiority when operated with feeding and dispersing systems, that guarantee for best adaption to the product sample.
